I got it! I made the following mistake: I have a static front page and my blog posts of the main blog (where the aggregated posts from the network sites should appear) appear in another page. I tried to access the tag-filtered posts via http://site.url/dedicated_page/tags/foo and that didn’t work. Instead, you have to use http://site.url/tags/foo !!
EDIT:
Right, I just found out myself: Adding
/^(entry[\d-]+)\.txt.gz$/ && system("gunzip -fv $dir/$_");
after line 623 in import_dir unzips the postings. I had to rerun the script afterwards to do the import, I’m sure there is a way to do it in one step, but I don’t know much Perl and that did the trick for me. Thanks for the cool script!
As far as I can see, this script only works, if the postings are just in text files, not but in zipped text files (*.txt.gz). I tried unpacking manually one posting and the import with the script works like a charm for this posting. So my question is, what do I have to change in the script to let it unpack the posting files first?
